Capture NX

Capture NX is an image editing application developed by Nik Software in partnership with Nikon for macOS and Microsoft Windows.
In September 2012, Google acquired Nik Software. Capture NX remained branded as a Nikon product.
In July 2014, Nikon released Capture NX-D to succeed Capture NX 2. As such, the Nikon D810 is the first camera to support only Capture NX-D. Capture NX-D was developed based on SILKYPIX Developer Studio and does not contain the U-Point technology from Nik Software.
On June 6, 2022, Nikon announced that Capture NX 2 and Capture NX-D would be discontinued and replaced by NX Studio. Download links for both programs were removed on June 30, 2022.
